Based on what I read on the other site, they got criticized for being disruptive during the play.
Hope it will not affect the show even though the filming had ended.

Tbh, OYS was meant to be killed as he and VIP had different ideology. He is just a pawn in this game.
The driver could be under instruction to finish him off when situation is getting out of hand.
